My son Grant is two weeks old. He is starting to have problems sometimes latching on. He will root around on my breast and take my nipple in his mouth, and then spit it out. He gets very mad at this and I try everything to get him to latch on. After a few minutes, and a huge fit, he will finally latch on. Is there something that I'm doing wrong? I don't know if the milk is coming out too fast for him and he's drowning or what.
